Abstract: The present invention involves an improvement in a conventional drum brake assembly which utilizes a pair of brake shoes separated by an adjustable strut. A parking brake lever (4) is pivotally attached to one of the brake shoes and when it is rotated in a braking direction, causes both brake shoes to expand by interacting with the adjustable strut. A plate spring (12) attached to a backing plate (1) allows the parking brake lever (4) to pass in the braking direction after assembly of the drum brake, thereby removing slack and properly adjusting the drum brake. The plate spring (12) can be displaced from outside the drum brake to allow the parking brake lever (4) to pass in the opposite direction for disassembly of the drum brake.

Abstract: The alkoxidation products of amines, oils and fatty acids with alkylene oxides prepared by known processes have high alkylene oxide and 1,4-dioxane contents. This is undesired from possible toxicological points of view. The novel process should not have these disadvantages. For this purpose, a process is proposed in which the fatty alcoholates obtained in the alkoxidation by direct reaction of alkali metal hydroxide with fatty alcohols are used as catalysts. The products prepared by this process have residual contents of alkylene oxide of below 10 ppm and 1,4-dioxane of below 100 ppm.

Abstract: A radiant electric heater has one or more infra-red lamps (22, 24) having a relatively high temperature coefficient of resistance. To reduce the inrush current when the lamps are first energized, a series resistance coil (54) is provided together with circuitry (64, 66, 68, 70) to bypass the series resistance after a short time interval. Because the energy dissipated in the coil is relatively limited, it can be concealed beneath a peripheral insulating wall (18) of the heater.

Abstract: Apparatus and method are described for restoring convolution degraded signals such as blurred images produced by defocused cameras and moving objects. The degraded signal is first processed by a noise reduction means to reduce noise. Then various derivatives of the degraded signal are computed. Each derivative thus computed is multiplied by a corresponding weight parameter to give a weighted derivative. All the weighted derivatives are then summed to obtain a restored signal. The weight parameters themselves are computed based on the moments of the convolution kernel. 
     The apparatus of the present invention comprises a noise reduction means, a weight parameter computation means, a multiplication means, and a summation means. 
     The computations involved in the method of the present invention are local in nature and do not involve computing Fourier transforms. Hence the method and the apparatus of the present invention are efficient and less expensive than conventional methods and apparatuses.

Abstract: Optical transmitter comprising a control loop for fixing the bias current of the amount of light emitted by a laser diode 6, a cascade circuit 5 of the laser diode 6, a photodiode 7 and a variable gain factor amplifier 8 being included in the negative feedback path of the control loop. 
     By feeding a modulation signal to the summator 4, the laser diode may be amplitude modulation. To avoid that the control loop cancels the mean value of the modulation signal, a cancelling signal c of such a magnitude that the output signal of the control amplifier is independent of the modulation signal is applied to the input of the control amplifier 3. 
     For deriving this cancelling signal from the modulation signal in a fixed manner, the transfer factor of the negative feedback path is fixed by the transfer of the negative feedback path for an auxiliary signal, to be measured by means of a comparing circuit 12 and, on the basis of the result of this measurement, by adapting this transfer factor in that the gain of amplifier 8 is adjusted.
